As Charlotte and Heidi were teaching two groups of 3-4 year olds (a class of 16 and one of 17), they gave a tooth brushing demonstration with an oversized toothbrush and large set of teeth. The children really got into it and enjoyed the exercise where they got to sort food into good for you and bad for you hoops! The school visits really help to make learning fun and the children really get stuck in to the activities :-)
